CCS/TM4C1294NCPDT: I2C can't read true temperature value

Tool/software: Code Composer Studio

I can observe i2c clock signal on oscillascope it works fine. It means that i send data master to slave. 

I use lm75a as a slave device which is temperature sensor. I have issue about reading data from slave. I read value but it does not change. It means it is not temperature or what value am i reading?

My code is shown below:

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_i2c.h"
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"

#include "driverlib/i2c.h"
#include "driverlib/pin_map.h"
#include "driverlib/sysctl.h"
#include "inc/tm4c129xnczad.h"

#define SLAVE_ADDRESS 0x00
